This will solve 2d photonic crystal modes by plane wave method

听觉模型的仿真软件，很好用的ear模型，HUTear模型(Auditory model simulation software, the good ear model, HUTear model)

说明：  matlab求解整数线性规划，能够求解任意的方程的解 (matlab solving integer linear programming, to solve the arbitrary equation)

该程序实现了几种线路码的编译过程。包括编码和译码的过程，绘制有关的性能曲线、频谱图和波形图，还有纠错的能力。(the realization of several lines of code compile process. Including the coding and decoding process, drawing on the performance curve, spectrum and waveform charts along with error-correcting capabilities.)

matlab教程，线性代数部分，很全很有用，特别是对于解线性方程组，赶快收藏啊！(matlab tutorial, linear algebra part, it is all very useful, especially for solving linear equations, hurry collection ah!)

用风电功率历史数据来对未来一段时间功率的数值进行预测，通过Matlab软件编程和Excel处理数据，用神经网络仿真预测法、灰度预测法、时间序列预测法通过历史数据所呈现出来的一些规律对某段时间的风电功率展开预测，预测之后对得到的数据进行误差分析，通过与一些标准的对比来确定预测方法的可靠程度(Using historical data to forecast wind power to the value to the future time power, by Matlab software programming and Excel data processing, neural network simulation and prediction of wind power law method, gray prediction method, time sequence prediction method based on the historical data are presented for a period of time after the start prediction, prediction the data are error analysis, by comparing with the standard to determine the degree of reliability prediction method)
